Let's
simplify step-by-step.
3x2(x2−4x−4)+5x3+7x2+2x+11
Distribute:
=(3x2)(x2)+(3x2)(−4x)+(3x2)(−4)+5x3+7x2+2x+11
=3x4+−12x3+−12x2+5x3+7x2+2x+11
Combine
Like Terms:
=3x4+−12x3+−12x2+5x3+7x2+2x+11
=(3x4)+(−12x3+5x3)+(−12x2+7x2)+(2x)+(11)
=3x4+−7x3+−5x2+2x+11
Answer:
=3x4−7x3−5x2+2x+11

Answer:
the rate compounded semi-annually is compounded twice in a year. thus, this rate is higher than the rate compounded annually which is compounded once in a year
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r/m)^mn
FV = Future value  
P = Present value  
R = interest rate  
N = number of years 
m = number of compounding
For example, there are two banks
Bank A offers 10% rate with semi-annual compounding 
Bank B offers 10% rate with annual compounding. 
If you deposit $100, the amount you would have after 2 years in each bank is 
A = 100x (1 + 0.1/2)^4 = 121.55
B = 100 x (1 + 0.1)^2 = 121
The interest in bank a is 0.55 higher than that in bank B

Answer:
31
Step-by-step explanation:
Multiply the numbers 7 * 4, which gets your 28.
= 28+6-12/4
Divide the numbers 12/4, which gets you 3
=28+6-3
Add/Subtract the numbers 28+6-3
= 31
